    • An improved hydraulic lifting sectional security door, capable of being installed at an entry space to a room, comprising a pair of profiles (PRF) near to each frame (STP) of the entry space, a series of panels (PNL) articulated together and a device or group (GP) for lifting the panels (PNL), which includes a hydraulic cylinder (CI), to which fixed and mobile lifting pulleys (PL1, PL2, PL3, PL4) are fixed; according to the invention the lifting cables (FA1, FA2) start from stops (FE1, FE2), which are preferably next to the cylinder (CI) and their exit in the direction of the return pulleys (PU1, PU2) takes place in a balanced manner, on the two outer sides of the lifting pulleys (PL1, PL2, PL3, PL4), so as to be able to obtain a reversible container (CAS), which allows the hydraulic cylinder (CI) and the exit of the hydraulic tube (TU) to the right or left of the entry space, according to the user's desires and requirements.
    • 一种改进的液压提升截面安全门,能够安装在进入空间的房间中,包括一对在入口空间的每个框架(STP)附近的型材(PRF),一系列面板(PNL)铰接在一起, 用于提升包括液压缸(CI)的面板(PNL)的装置或组(GP),固定和移动提升滑轮(PL 1,PL 2,PL 3,PL 4)被固定到该液压缸 根据本发明,提升电缆(FA 1,FA 2)从停止(FE 1,FE 2)开始,其优选地与气缸(CI)相邻,并且在返回滑轮(PU 1,PU 2)在起重滑轮(PL 1,PL 2,PL 3,PL 4)的两个外侧平衡地进行,以便能够获得可逆容器(CAS),这允许液压 气缸(CI)和液压管(TU)的出口位于进入空间的右侧或左侧,可根据用户的要求和要求。
